3.3 RECEIVERS

If any camera you want to install is PTZ cap- able, then the receiver for that camera must be individually wired for power and control (depen- dent on type). The CM9760-SAThas built-in software that is individually selectable for each camera control type. The correct protocol is se- lected via menu choices when programming the Cameras menu for each individual input (see Section 2, Camera Programming Menu-Page 2 of 2 ). Allowed camera control types must be able to utilize one of two communication proto- cols for connection to the SAT. One control type is Coaxitron® . Coaxitron (standard or extended) receivers utilize the input video line as a path for sending control commands to the receiver.

The other control type is RS-422 “P” protocol receivers that are wired independent of the video path. RS-422 command control connec- tions originate at COM 1 on the rear of the SAT (see Figures 1 and 1-8).

3.4 ALARMS

The SAT has 16 alarm inputs, each designed for use with standard single-pole, single-throw (SPST) switches. The alarm inputs on the connector correspond, on a one-to-one basis, to the SAT’s 16 video inputs; that is, video input 1 corresponds to alarm input 1, video input 2 corresponds to alarm input 2, and so on. To properly recall alarmed video, each alarm connection must correspond to the cor- rect video input. Each must also be appropriately programmed for a number of variables. Refer to Section 2, Alarm Programming Menu-Page 1 of 1.

Connect the alarm inputs as illustrated in Figure 1-9. Alarms 1-9 use the indicated 12-pin con- nector (provided). For each alarm-video pair in- stalled and accounted for, wire a return ground path. Utilize a ground connection located on the same connector on which your alarm input is wired. Proceed on a pair-by-pair basis until all video-associated alarm pairs are wired. Utilize both alarm wiring connectors, if necessary.
